3 Pins Controlling 14 (Shift Registers)

Anyways! I’ve set aside my home automation project and picked up a few of these shift registers: the 74hc595 by TI, seen here:

As seen in the video above, I’m controlling 14 led’s using two of the 74hc595s and and 3 pins on an Arduino Uno.

The program uses a for loop and cycles through the 14 pins on the registers. That code can be found here. Thanks for reading, check back soon for updates on the home automation project.

Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone, but proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
